(CNN) -- Bayern Munich are set to sign Dutch international winger Arjen Robben from Real Madrid on Friday.

Robben is poised to join Bayern Munich after a fee of $36 million was agreed with Real Madrid.

The German Bundesliga giants have announced that former Chelsea wideman Robben will undergo a medical on Friday morning before signing a four-year contract.

Bayern's general manager Uli Hoeness confirmed that a fee, reported to be in the region of 25 million euros ($36m), has been agreed between the two clubs and only a few minor details needed to be ironed out in the morning.

"He is on the way to Munich," confirmed Hoeness on the club's official Web site. "It is right that we are interested in signing Arjen Robben.

"We have already reached an agreement with Real. He is one of the best attacking midfielders around in Europe and he has always been the player we wanted."

Robben could be included in coach Louis van Gaal's squad to face Wolfsburg at the weekend and may make an immediate debut.

Robben, who joined Madrid from Chelsea two years ago, has also spoken about the switch and while he admitted that he was reluctant to leave the Spanish giants, he was excited by Bayern's offer. The former PSV Eindhoven player told reporters: "I didn't want to go but the club wanted to sell me.

"There have been many lies but in the end I also have to decide what's best for myself because I also want to play and show what sort of player I am. Munich have given me a very good feeling."

Meanwhile, it was a busy day in the English Premier League, with plenty of clubs doing transfer business ahead of Tuesday's transfer deadline day.

Aston Villa have completed the signing of Blackburn defender Stephen Warnock for an undisclosed fee -- believed to be around $13 million.

England international Warnock has put pen-to-paper on a four-year contract which will keep him at Villa Park until the summer of 2013.

Blackburn manager Sam Allardyce moved quickly to replace Warnock, swooping for Tottenham's French defender Pascal Chimbonda on a two-and-a-half year contract.

Villa manager Martin O'Neill is also set to add Manchester City captain Richard Dunne to his squad. Villa have reached agreement with City over a fee for 29-year-old Dunne -- who is expected to lose his place following City's signing of Everton defender Jolean Lescott.

Villa were also thought to be keen on Portsmouth central defender Sylvain Distin, but Everton have agreed a three-year deal for the Frenchman, who will come in as a direct replacement for Lescott at Goodison Park.

Struggling Portsmouth, who have lost their first three league games of the season, have been busy signing players as well, bringing in forward Tommy Smith from Championship club Watford on a four-year seal for an undisclosed fee and making a bid for his defensive team-mate Mike Williamson.

Elsewhere, Stoke City have also been busy in the market, signing German defender Robert Huth from relegated Middlesbrough and putting in place a deal to sign Turkish international forward Tuncay Sanli from the same club, for a combined fee of $18m.

Meanwhile, Fulham have completed the signing of South African international midfielder Kagisho Dikgacoi for an undisclosed fee on a two-year deal.
